[Abstract] Objective: To explore the differences of fractional amplitude of low-frequency fluctuation (fALFF) between seafarers and health people, by using the technique of resting state functional magnetic resonance imaging.Materials and Methods: All the subjects were divided into three groups, mental sub-health seafarers(subHS), health seafarers(HS) and health people(HP). Then calculate the fALFF of each subject, Finally, a statistical method was used to find the voxels which had significant difference between control group according to the Anatomical Automatic Labeling(AAL) template.Results: As a special profession, the brain activity of seafarers has plasticity. the main difference of seafarers’ fALFF were concentrated on parietal lobe compared with HP. the difference of fALFF on parietal lobe between subHS-HP were significantly decreased than that of HP-HS. Besides parietal lobe, the brain area of subHS including temporal lobe, precuneus and cingulate cortex also appear significant differences compared with HS.Conclusion: Engaged in offshore occupation for a long time may lead to the change of brain functional activity, some seafarers even appear mental sub-health condition. The study can provide help for the protection of mental health of seafarers and the security of maritime operations.
